First evaluate
what angles in domain of [-pi/2, pi/2] make sin = 0
Now we can evaluate the cos function:
what angles in domain of [-pi/2, pi/2] make sin = 0
Now we can evaluate the cos function:
Answer:
Part a) The y-intercept is the point (0,20) and the x-intercept is the point (10,0)
The graph in the attached figure
Part b) See the procedure
Step-by-step explanation:
<u><em>The questions are</em></u>
Part a) Find the intercepts and graph the function
Part b) What does each intercept represent?
Part a) Find the intercepts and graph the function
Let
x-----> the number of hamburgers
y ----> the number of hot dogs
we have
Remember that
The <u><em>y-intercept</em></u> is the value of y when the value of x is equal to zero
so
For x=0
The y-intercept is the point (0,20)
The <u><em>x-intercept</em></u> is the value of x when the value of y is equal to zero
so
For y=0
The x-intercept is the point (10,0)
Plot the intercepts and graph the line
see the attached figure
Part b) What does each intercept represent?
The x-intercept is the number of hamburgers they can buy if they buy no hot dogs
The y-intercept is the number of hot dogs they can buy if they buy no hamburgers
